My issue is then I retrieve my NSArray of Store objects, all my NSString properties are causing BadAccess errors. The int and double properties work fine!
store.h
@interface Store : NSObject<NSCoding> {
NSString *Name;
NSString *Address;
NSString *Phone;
double GeoLong;
double GeoLat;
int ID;
}
@property (nonatomic, retain) NSString *Name;
@property (nonatomic, retain) NSString *Address;
@property (nonatomic, retain) NSString *Phone;
@property (nonatomic) double GeoLat;
@property (nonatomic) double GeoLong;
@property (nonatomic) int ID;
@end
store.m
@implementation Store
@synthesize Name;
@synthesize ID;
@synthesize Address;
@synthesize Phone;
@synthesize GeoLat;
@synthesize GeoLong;
/** Implentation of the NSCoding protocol. */
-(void)encodeWithCoder:(NSCoder *)encoder
{
[encoder encodeInt:ID forKey:@"ID"];
[encoder encodeDouble:GeoLat forKey:@"GeoLat"];
[encoder encodeDouble:GeoLong forKey:@"GeoLong"];
NSLog(@"Name in encode: %@", Name); //WORKS!
[encoder encodeObject:Name forKey:@"Name"];
[encoder encodeObject:Phone forKey:@"Phone"];
[encoder encodeObject:Address forKey:@"Address"];
}
-(id)initWithCoder:(NSCoder *)decoder
{
// Init first.
if(self = [self init]){
ID = [decoder decodeIntForKey:@"ID"];
GeoLat = [decoder decodeDoubleForKey:@"GeoLat"];
GeoLong = [decoder decodeDoubleForKey:@"GeoLong"];
Name = [decoder decodeObjectForKey:@"Name"];
NSLog(@"Name in decode: %@", Name); //WORKS! logs the name
Address = [decoder decodeObjectForKey:@"Address"];
Phone = [decoder decodeObjectForKey:@"Phone"];
}
return self;
}
- (void)dealloc
{
[Name release];
[ID release];
[Address release];
[Phone release];
[super dealloc];
}
@end
Here is my code for storing and retriving the array.
//streams contains the data i will populate my array with.
for (ndx = 0; ndx < streams.count; ndx++) {
NSDictionary *stream = (NSDictionary *)[streams objectAtIndex:ndx];
Store *item = [[Store alloc] init] ;
item.Name = [stream valueForKey:@"Name"];
item.Address = [stream valueForKey:@"Address"];
item.Phone = [stream valueForKey:@"Phone"];
item.GeoLat = [[stream valueForKey:@"GeoLat"] doubleValue];
item.GeoLong = [[stream valueForKey:@"GeoLong"] doubleValue];
item.ID = [[stream valueForKey:@"ID"] intValue];
[listToReturn addObject:item];
}
}
//test to check if it works
for(int i = 0; i < [listToReturn count]; i++){
Store *item = (Store *)[listToReturn objectAtIndex:i];
NSLog(@"Name: %@", item.Name); //works
}
//save
[[NSUserDefaults standardUserDefaults] setObject:[NSKeyedArchiver archivedDataWithRootObject:listToReturn] forKey:@"stores"];
// retrieve
NSMutableArray *stores = [NSMutableArray new];
NSUserDefaults *currentDefaults = [NSUserDefaults standardUserDefaults];
NSData *dataRepresentingSavedArray = [currentDefaults objectForKey:@"stores"];
if (dataRepresentingSavedArray != nil)
{
NSArray *oldSavedArray = [NSKeyedUnarchiver unarchiveObjectWithData:dataRepresentingSavedArray];
if (oldSavedArray != nil)
stores = [[NSMutableArray alloc] initWithArray:oldSavedArray];
else
stores = [[NSMutableArray alloc] init];
}
if ([stores count] > 0) {
NSMutableArray * annotations = [[NSMutableArray alloc] init];
for(int i = 0;i< [stores count]; i++){
Store *store = [stores objectAtIndex: i];
CLLocationCoordinate2D location;
if(store.GeoLat != 0 && store.GeoLong != 0){
location.latitude = store.GeoLat;
location.longitude = store.GeoLong; //works
NSLog(@"Adding store: %@", store.Name); //DONT WORK!! <-- MAIN PROBLEM
}
}
}
Feels like I tried everything but can't figure out how it works in the decode but not when in loop the array after I put it into a array.
Anyone have any ideas?
